There are personality traits inherent to successful CEO's that are in-born.

For example: I cannot imagine being a successful touring live performer. I am an introvert, I keep a rigid schedule so travel throws everything off, can't keep myself awake very late...

Could I perform the functions of a live performer? Yes, though no matter how much I "tried" the mismatch between the job and my natural tendencies is a recipe for failure.

Not everyone can be a CEO because not everyone is cut out for it. If you think you could step into those shoes, you're either built different or delusional.
